[Pharmacokinetic, behavioral and neurophysiological aspects of the action of 2-ethyl-6-methyl-3-hydroxypyridine in rats].

Specific features of 2-ethyl-6-methyl-3-hydroxypyridine (3-OP) action were investigated in white rats. A correlation has been established between pharmacokinetic parameters and basic manifestations of psychotropic 3-OP effect. Correlations have been also observed between the level of manifestation of anxiolytic effect and changes in 3-OP concentrations in the rat brain. Electroencephalographic findings of the nootropic effect in sensorimotor cortex correlate with 3-OP brain concentrations. The authors describe specific drug pharmacokinetics and possible mechanisms of realization of psychotropic effects.
